This invention relates to improvements in cushioning weather stripsparticularly adapted for use as a resilient seat for the upper edge ofthe Window of an automobile. The principal object of the invention is toprovide a simple, economical, durable and eflicient cushion strip andstrip mounting which may be easily and quickly assembled at the top ofthe window without the use of tacks, nails or other special fasteningspassing through the cushion and which tightly seals the closed windowagainst the admission of rain, wind or dust.

The special features of the improved cushion strip are hereinafterdescribed in connection with the accompanying drawing illustrating arecommended embodiment of the invention, and will be pointed out in theappended claim, it being understood that the structural details of theapparatus may be varied to suit particular purposes without departingfrom the essence of this invention N as defined in said claim. In thedrawing,

Fig. 1 is a perspective view of the improved view snowing the top of hatthe cushion strip;

that of Fig. 2 showing ushion and weather strip of a piece of rubbertubally rectangular in cross section but g side walls 6 divergingoutwardly from T use or rear wall 7'toward its front face 8. 1 e base ofthis hollow strip is provided with integral side flange 9 providing alongitudinal channel 10 between the flange and one of the sides 6.

The base 7 of the strip isapplied against ,w the under side oi the upperwindow frame 11 a as shown in Fig. 2 and a retaining plate 12 isfastened to the frame as by screws 13 with one inwardly bent side 14:engaging in the channel behind the flange 9 and against one side 6 ofthe rubber strip. The opposite side of the strip bears against adownward projection 15 of the frame, which may be sheathed by a metalfacing 16; and the rubber tube is transversely compressed between theabutment 15 and the flange 14 of the garnishing plate or molding 12 sothat its sides 6 are substantially parallel. Hence the front 8 of thecushion is cupped or concaved (Fig. 2) by the lateral constriction ofthe relatively wide front wall, thereby providing a longitudinaldepression for receiving the edge of the upwardly moving window pane 17.

As the pane 17 is elevated into engagement with the cushion, the cuppedfront wall 8 is depressed toward the back 7 and between the sides 6 ofthe cushion strip and the sides of the pane. An unusually tight seal isthus afforded, and it is apparent that the pane is safely and securelyheld in position, thus reventing damage to the window and avoi ing anytendency of the pane to rattle or shake. This feature is particularlyimportant in the windows of automobile doors which are subjected toconsiderable vibration duringdriving and to abrupt ars when the door isopened or closed. @bviously the yielding nature of the compressiblecushion obviates shock to the pane and at the same time preventsexcessive lateral displacement of the window.

In the modified form illustrated in Fig. 4, the side flange 18 of thecushion base 7' projects rearwardly as well as laterally of the rnbberstrip, and the rearward projection is fitted within longitudinal recess19 of the frame 11. In this case, the molding flange 14 forces therubber flange, 18 into the frame recess, thereby providing a more secureanchorage which eliminates any likelihood that the cushion may bedislodged from the frame or displaced from proper position until theanchoring plate 12 is removed.

From the foregoing it is apparent that the hollow cushion strip isinexpensive to manufacture and easy to install or remove; the ab senceof tacks or other fastenings passing through the rubber avoids damage tothe strip or impairment of its cushioning qualities; the yielding frontwall resiliently embraces the edge of the window pane and protects theglass from damage as well as providing a tight seal between pane: andwindow frame; and the cushion is fixedly secured by the anchoring plateso that it will not be accidentally dislodged from operative position.

5 I claim:

In combination with a window frame member having a longitudinal,inwardly pro- ]ecting abutment, a cushioning weather strip for the topof a sliding window pane, comprising a tubular, four-sided cushion stripof resilient material having its rear Wall engaging the under surface ofthe frame and one side wallengaging said abutment, the rear wall havingan integral, laterally projecting flange providing a longitudinalchannel, and a molding strip fastened to the under sur face of the frameand having a rearwardly directed flange extending along the oppositeside wall of the cushion strip and having its free edge engaging in saidchannel to clamp the cushion strip against the frame, the bottom of theframe having a. recess extending longitudinally of the cushion strip andthe flange of said strip having a rearwardly pro- 'ecting portionreceived in said recess therey to prevent lateral displacement of thestrip.

In testimony whereof I aflix my signature.

MYRON O. SLEEPER.
